33 Claims.

This invention relates to tabulating machines and more particularly toimprovements in the printing mechanisms therefor.

Tabulating machines, as presently developed, are provided withprintingmechanisms whereby numerals represented by index point perforations maybe indicated by printing upon a record strip, and, in addition thereto,such printing mechanisms are also employed to represent the result ofsome computation, such as a total of a series of items. It frequentlyhappens that it is desirable to identify the printed items orcomputations by printed words or the like and in some instances this canreadily be accomplished by substituting letter type for the numeralbearing type so that the index points will represent alphabetical orother characters. Due to the limitations in the number of index pointsin a card column, which is usually ten, a limited number of charactersmay be printed detracting from the useiulness of such an expedient.

It is then the main object of the present invention to extend theusefulness of such printing mechanisms by providing an improved printingmechanism which may be called upon when occasion requires to printeither numerals or alphabetical characters.

It is a further object of the present invention to provide an improvedform of differential type controlling mechanism designed to becontrolled by a single card column which may select for printing eitheralphabetical or numeral characters arranged in groups, which charactersare far in excess of the number of index points in a card column.

It is a further object of the present invention to provide improvedmeans whereby group selection and type selection occur during successivecard feeding cycles and by separate analyzing means. In order to carryout the above object correlated reading-in and reading-out commutatorsor translators are provided. Thus one set of brushes may control groupselection during one card cycle while another set may select a desiredtype of the selected group during the next card cycle.

In carrying out the present invention, the preferred means comprises atype carrying member provided with a plurality of groups of type, onegroup for example, being numeral type, the second, letters of thealphabet and the last, if so desired, other letters of the alphabet. Thenumeral group of type are normally presented to the printing point sothat as the card perforations register with the lower analyzing brushesthe type will be differentially selected. If a group selectingperforation should register with an upper or group analyzing brush thereading-in translator will cause the energization of the magnet relatedto the reading-out translator. This setting is held over by thereading-out translator until the card containing the group controllingperforation is presented to the lower or usual analyzing brushes. Thisresults in the selection of a particular type in the desired group. Inthis manner the card controlling columns may differentially control anumber of type to make up, for example, either a number, word, orabbreviation.

These and other incidental objects which will be pointed out hereinafterwill be clear from the following detailed description, in which:

Referring to Fig. 1 drive shaft 25 driven by the tabulating motor TM(Fig. 4) carries a box cam 26 the race of which reciprocates a lever 27loose on a rock shaft 28. Fixed to the shaft 28 is a bell crank 29having a projection 30 in engagement with a screw carried by lever 27.In this manner a reciprocation of lever 27 by cam 26 will rock shaft 28and levers 31 carried thereby. The ends of the oscillatory levers 31 areconnected by links 32 to a cross head 33 and imparts vertical movementthereto as fully disclosed in the Lake Patent No. 1,379,268 dated May24, 1921.

Extending from the cross head 33 are arms carrying a bail 34 which isadapted to control the upward movement of a slidable plate 35 which atits lower end is guided by a pin 36 carried by a bent integral portionof plate 35. The shank of pin 36 protrudes through a slot 3'7 in a plate38 and the pin has an enlarged head overlying the face of plate 38. Atits upper end plate 35 has an integral projection 39 suitably recessedto receive the rack portion 40' of a type carrying plate 41, oneedge ofplate 41 being bevelled at 42 to receive a similar internal bevel of theoverturned portion of projection 39. Plate 41 has an elongated slot 43receiving a pin 44 which is similar to pin 36 but is carried by anextending portion of plate 38. The upper portion ofplate 41 is alsoguided by a slotted bar 45. Mounted on plate 38 forengagement with therack portion 40 of plate 41 is a pinion 46 also in continuous engagementwith a rack portion 47 of plate 35. Considering plate 38 fixed it willbe obvious that a movement of plate 35 causes an opposite and equalmovement of plate 41.

Bar 34 engages the shoulders 48 of the plates 35 and plates 35 arenormally drawn upwardly by spiral springs 49 connected to them throughlinks and levers 50 and, therefore, are in contact with the bail 34 andfollow the upward movement of the latter imparted by levers 31 untilarrested by pawls 51 operated by magnets 52 and engaging in one of aseries of notches'53 in the side edges of plates 35.

The spacing of thenotches 53 corresponds with the spacings ofthe typebars 54 constituting numeral type bars of group A. It will be clear thatas plate 35 moves differentially the rack. portion 47 thereof will drivepinion 46 thus moving plate 41 oppositely br nging the desired type barin correspondence with the printing platen. The movement of type bars 54is synchronous with the movement of perforated cards through the machineso that when a perforation is encountered by a brush in the tabulatorthe corresponding magnet 52 is energized, as will be hereinafter setforth, and the plate 35 is stopped at a point in its upward travel and,therefore, bar 41 in its downward travel which brings the typecorresponding tosuch perforation into the printing position and holds itthere until after the print- The hammers proper comprise members 55pivoted on shaft 56 and drawn away from the type 54 by springs 57. Thehammers are adapted to be struck up by a striking bail 58 which isspring actuated by a spring 59. A link 60 connects bail 58 with arm 61and the bail'is locked in place by means of a trip finger 62 engagingarm 61. The finger 62 is pivoted upon the arm 31 and spring connectedthereto and provided with a pin 63 which engages with a coacting stoppin 64 fixed to the frame of the machine so as to trip off the notchedend 65 of the lever 62 from the depending fingered end of arm 61 whenlever 31 is being elevated. After notch 65 is completely disengaged, thespring 59 swings the bail 58 in a counterclockwise direction and impelsthe hammers 55 against the type. The hammer details form no part of thepresent invention and for further details of construction reference maybe had to the application of C. D. Lake, Serial No. 541,347 filed March6, 1922.

Movable with the reciprocatory frame 33 is a cross bar 66 having a rod67 upon which are pivoted spring urged pawls 68 normally engagingprojections 69 of each of the plates 38. When numeral type of group A,for example, are selected for operation each pawl 68 is engaged by ashoulder 70 of a related hooked member 71 so that as bar 66 rises pawl68 will be rocked to disengage its upper end from the projection 69 sothat as cross bar 66 rises further the latter will not elevate plate 38.Plate 38. will then be held impositively by a pawl 74 engaging a notch75.

When the frame 33 has reached its extreme'upward position it isreversely moved by the levers 31, the bail 34' engaging the projections48 of the various din'erentially elevated plates 35 restoring them alsoto normal. As each plate 35 is moved downwardly the inclined edge of oneof the notches 53 will cam the stop pawl 51 to its normal latchedposition. As cross bar 66 returns to its normal starting position pawl68 will again latch over projection 69 of plate 38. If a magnet 72a isenergized prior to the elevation of cross bar ,66 hooked member 71 willbe rocked by a call rod 72 attached thereto and moved by the armature ofthe magnet. As crossbar 66 rises thereafter pawl 68 will raise plate 38.As bail 34 rises spring 49 will be effective to permit plate 35 tofollow the movement of said bail, and type carrying plate 41, plates 35and 38 moving upwardly asa unit will bring type bars of group B incorrespondence with the platen and if plate 35 is not stopped in itsupward movement by the engagement of a pawl 51 with one of the notches53, type carrying plate 41 will be elevated until the lowest type bar ofgroup B will be at the printing point. At a definite position of theplate 38 pawl 68 (Fig. 2) will engage an upper hooked portion 73 ofhooked member 71 rocking pawl 68 out of engagement with the projection69. As plate 38 reaches a predetermined position it is.- heldimpositively by pawl 74 engaging the inter mediate notch 76 in the sideof plate 38.

In the event that magnet 52 should be energized during the elevation ofplate 35 pawl 51 will engage one of the notches 53 thus stopping themovement of plate 35. Since plate 38 is rising pinion 46 will roll in aclockwise direction over the stationary rack portion 47 thus elevatingplate 41, but not to the same extent as before to present the desiredtype to the printingplaten. Describing the operation more in detail itwill be clear that if character L is to be selected for printing bar 35will be checked almost immediately so that as plate 38 rises it willroll pinion 46 clockwise over the rack portion 47 thus elevating plate41 at double speed so that as pawl 74 engages notch 76 the lowermosttype L of group B will be at the printing point. If the next character Kshould be selected for printing, bars 35 and 38 will be simultaneouslyelevated a unit before the former is checked. Thereafter the elevationof plate 38 alone will raise bar 41 to present character K to theprinting point. For the selection of the printing character E, plate 35and plate 38 will be moved simultaneously to directly present typecharacter E to the printing point at which time plate 35 will be checkedagainst further upward movement by pawl 51 and plate 33 by pawl 74. Forthe remaining characters A, B, C, or D,

the movement is composite, that is, it is the same as when typecharacter E is selected for opera tion with the exception that plate 35may then rise independently of plate 38 since it is not checked by pawl51. As it rises under control of bail 34 it will depress bar 41 toselect the proper type, the extent of this movement depending upon thetime that plate 35 is checked by pawl 51.

As bar 33 approaches its maximum elevated position (shown by dottedlines in Fig. 2) pawl 68 will be entirely disengaged from the hook 73and will strike a bar 78 (see Fig.3) at the extreme upward position ofbar 33. Restoration of the parts is performed as premised hereinbeforewith the exception that a portion 79 of frame 33 engages projection 69to restore plate 38 to the position shown in Fig. 1. In the abovemanner, any of the alphabetical characters A, B, C, D, E, F, H, J, K orL may be selected for printing.

The type carriers for printing the alphabetical characters, M, N, P, R,S, T, U, W, X, Y, constituting group C are selected in a similar manner,it being observed in this instance that magnet 72a will be retainedenergized during, the time bar 66 is raised upwardly which serves tokeep the hooked ends 70 and 73 from engaging pawl 68, the latter beingeffective to raise plate 38 from the position shown in Fig. 1 to theposition shown in Fig. 3 this position of plate 38 being imposi tivelyheld by pawl 74 engaging notch 77. The selection of any of the type barsfor printing any of the alphabetical characters constituting group C isprecisely as described heretofore. Restoration of the parts brings themto the position illustrated in Fig. 1 where the numeral type of group Amay be normally selected for printing.

The construction and operation of the translator mechanism forcontrolling the energization )f magnet 72a will be explained inconnection with Figs. 4, 5, and 6 of the drawings. A complete unit for adenominational order is illustrated in Fig. 5, the commutator beinggeared to the commutator 80a with a one to one ratio, the commutatorsbeing, driven from one of the driving shafts of the machine and insynchronism with the card feeding operations.

The mechanical structure of the reading in commutator 80 may best beunderstood from Figs. 4 and 5 of the drawings. A stud 81 fixed to thebase plate of the unit rotatably supports the com mutator structurewhich includes a central metal portion 82 to which is attached thecommutator driving gear 83 and the cup-shaped insulating body portion84.

For each denominational order the insulating body portion is providedwith two grooves 85 in which ride the stationary brushes 86 and 87 whilea stationary brush 88 contacts the periphery of the metal portion 82.The brushes 86, 87 and 88 are all carried by and are mounted upon aninsulated brush holder 89 fixed to the base plate. A plurality of metalpins 90 and 91 are inserted through the metal portion 82 and insulatingbody 84 and have their heads exposed in the grooves 85 to contact withtheir related brushes 86 or 87.

The pins 90 and 91 are not only spaced axially to contact with theirrelated brushes 86 or 87 but are displaced angularly about the peripheryof the insulating body portion 84. The spot 90 is timed so as to contactwith brush 86 when the 11th position of the card (see Fig. 7) is inregistration with one of the upper controlling brushes 92 (Fig. 4) whilespot 91 contacts its related brush 87 when the 12th position of the cardis in registration with the same brush 92. It will be apparent,therefore, that if a perforation should be at either the 11th or 12thpositions the corresponding spot 90 or 91 will permit the energizationof a magnet 98 or 94 by a circuit now to be traced.

Referring to Fig. 4 the machine circuits are energized from a source ofenergy indicated at 95 connected to the circuits through a double poleswitch 96. Upper brushes are energized through cam contacts 97 whichclose during the feeding of cards and open between successive cardcycles. Brushes 92 are, of course, electrically connected in somesuitable manner to sockets 98 connecting the pairs of magnets 93, 94 andin the present instance. the connection is exemplified by the Jumperconnection 99 thus electrically connecting brushes 92 and magnets 93 or94. By either of the spots 90 or 91 the circuit then extends by brush 88and wire 100 to the usual cam contacts 101 to the other side of theline.

The construction of one of the reading out commutators 80a isillustrated in Figs. 5 and 6. The commutator 80a is rotatably mounted ona stud 102 and driven by a gear 103. The commutator is provided with araised portion 104 provided with four circumferential grooves. A pair ofconducting annuli or metal tracks 105 and 106 are located at the bottomof two of these grooves, a pair of brushes 107, 108, and tracks 105,106, being provided for each denominational order. Attached to theraised portion 104 is a grooved metal wheel 106a electrically connectedto the tracks 105 and 106. A brush 106b is adapted to engage the groovein wheel 106a. The commutator is cut away for substantially one half ofits periphery and when this cut-away portion is opposite the brushes 107and 108 these brushes are free from contact with the commutator.

When the raised portion is opposite a particular brush that brush ridesin either a plain or metal tracked groove depending on the energizationstatus of related magnet 93 or 94. Each brush 107 or 108 is mounted on apivoted lever 109 urged by a spring 110 to cause the movement of therelated brush 107 or 108 into position to cause the brush to ride on ametal track 105 or 106. This lever is provided with an extension 111which coacts with a latch lever 112 on the pivoted armature structure ofthe associated magnet 93 or 94. The armature supporting structure isurged by a spring 113 to the position shown in Fig. 6 in which the latchmember 112 engages the extension 111 of the lever 109 and holds thelatch in position to guide the brush 107 or 108 to one of the plaingrooves.

When either the magnet 93 or 94 is energized to attract its relatedarmature the latch 112 will be disengaged from the extension 111permitting spring 110 to be effective to shift lever 109 to cause it tomove either brush 107 or 108 to engage the metal track 105 or 106,respectively, depending upon which magnet 93 or 94 is energized. It willbe understood that these shifting operations occur when brushes 107 or108 are opposite the lower portion of commutator 80a. Just after thebrushes 107 or 108 leave the grooves in the raised portion of thecommutator a cam 113a mounted on the gear 103 encounters a pivoted arm114 whose end engages the lever 109 and rocks it to restore the lever109 to the position shown in Fig. 6, thus restoring the brush to itsnormal position.

The operation of the device will now be explained in connection with thecircuit diagram illustrated in Fig. 4 and which is similar to thatdisclosed in the co-pending application of G. F. Daly and R. E. Page,Serial No. 6,980, filed Feb. 5, 1925, the circuits being altered toinclude the new mechanism to realize the present advantages. The circuitconnections by which magnets 93 or 94 are energized when either aperforation at the 11th or 12th position registers with one of the upperbrushes has previously been described.

The card columns controlling printing may or may not contain these extraperforations but have the usual perforations for differentiallyselecting a particular type bar of the desired group. These perforationsare sensed by lower brushes 115. These perforations close the countermagnet circuits traced as follows for one column, from the left side ofthe line, wire 116, contacts 117, counter magnet 118,'brush 115, commonbar 119, wire 120 to the right side of contacts T2, T3, and when thefirst card is being listed, through contacts T4, T5, by wire 121 tobinder post 11.

If a tabulating operation is being performed on a card other than thefirst card of a group the current instead of passing through T4 and T5will pass through T2 and T3, wire 135, brush 136, segment 137 throughcommutator 138, brush 139, wire 140 to binder post 11.

After the machine has operated a certain extent contacts Tl close,extending the circuit Just described from the binder post 11 throughupper and lower card lever contacts 122 and 123, closed contacts Tl,binder post 9, closed contacts P3 to the other side of the line.

The energization of counter magnet 118 sets up a supplementary circuitas follows: from the left side of the line contacts 125, printer magnet52, common bar 126, wire 127 to non-list switch 634 closed when listingis desired. With this switch closed, during the first card cycle andwith commutator circuit 139, 138, and 143 closed during the same cardcycle, current would be supplied from binder post 11 to the common bar119 through wires 142 and 141, contacts LPl now closed and throughswitch 634. In this way magnets 52 are provided with a return path forthe current which, as will be understood, is a secondary circuit whichhas been completed by the energization of the counter magnets from thebrushes and the subsequent closing of contacts 125.

It will be understood that if no other perforations appear in a cardcolumn aside from the usual perforation in one of the ten designatedpoints the numeral type in group A will be controlled diiferentially theparticular type selected depending upon the differential time thatprinting magnet 52 is energized; If a perforation should also appear inthe 11th position magnet 93 will be energized, as premised hereinbefore,which will release one of the levers 109 this releasing action occurringin the same machine cycle. As commutator 80a subsequently rotates brush107 will contact metal track 105 and current will then flow from theleft side of the line by wire 130, through magnet 72a, brush 106b, track106a, track 105, brush 107, and wire 131 to contacts 128 and thence bywires 132 and 142, brush 143 contacting with revolving commutator 138,brush 139, wire 140 to binder post 11 then to the other side of thesupply line as before. Cam contacts 128 are timed so that whenever thecard containing the 11th perforation is presented to the lower brushesthe contacts will subsequently close to energize magnet 72a at theproper time. This will result in the disengagement of hook (Fig. 1) frompawl 68 permitting the parts to be adjusted for selecting type of thesecond group which are then differentially selected according to thetime energization of magnet 52. Contacts 128 open however, prior to thetime that frame 33 reaches its uppermost position allowing hook 73 toagain engage the extension of pawl 68 (see Fig. 2).

If the controlling perforation should be at the 12th position theprinciple of operation is similar to that described heretofore with theexception that magnet 94 will be energized shifting brush 1,928,891 108to engage metal track 106. Magnet 72a is now in serial connection withcam contacts 129 by.

wire 134 and the cam controlling these contacts is preferably arrangedto keep magnet 72a energized retaining pawl 71 in the position shown inFig. 3. This results in a direct adjustment of the type carrying bar 41to differentially select the type constituting group C.

A relatively important phase of the invention is that the particularmeans provided for controlling group selection is active during adifferent card cycle than that in which type selection occurs. Thisdelayed action permits the upper brushes to be used for performing thefunction of group selection while during a subsequent card cycle thetype to be selected may be controlled by the lower brushes. Reading inand out commutators and 80a act, therefore, as delayed time relays, butit will be understood that other structures may be adapted to providefor the necessary delayed action.

While there has been shown and described and pointed out the fundamentalnovel features of the invention as applied to a single modification itwill be understood that various omissions and substitutions and changesin the form and details of the device illustrated and in its operationmay be made by those skilled in the art without departing from thespirit of the invention.
